United States Patent SLIVER COILING MECHANISM John S. Dudley, Douglas, Mass., assignor to Whitin Machine Works, Whitinsville, Mass., a corporation of Massachusetts Application November 10, 1953, Serial No. 391,206
2 Claims. (Cl. 19-159) This invention relates to machines in which slivers or loose strands of textile fibers are coiled in cans for transfer to machines which perform further operations thereon.
It is common in such machines to deliver the sliver to the can through a gear-driven coiler head having a downwardly and outwardly inclined and frusto-conical delivery passage.
It has been found desirable to use coiler heads with passages of different outlet diameters with the widely differing weights and compositions of slivers which are today commonly used.
It is the general object of my present invention to provide a single coiler head having a delivery passage of such improved design that it will satisfactorily deliver for coiling slivers of widely differing sizes and composition. The invention has been found particularly applicable to the coiling of worsted slivers.
My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.
A preferred form of the invention is shown in the drawings, in which- Fig. 1 is a sectional side elevation of parts of a coiler embodying my improvements;
Fig. 2 is a plan view of the coiler head, looking in the direction of the arrow 2 in Fig. 1;
Fig. 3 is a partial sectional elevation, taken along the line 33 in Fig. 2; and
Fig. 4 is a view similar to Fig. modification.
Referring to the drawings, I have shown a plate mounted on the frame F of a usual sliver coiler. A coiler head 12 is rotatably mounted on the plate 10 and is provided with a ring gear 14 which is engaged by a pinion 15. This pinion is continuously rotated by a drive shaft 16 through bevel gears 17 and 18. The usual direction of rotation of the head 12 is indicated by the arrow 4!.
The head 12 has an upper portion 20 defining a delivery passage 21 which is frusto-conical in section, and the axis of this passage is inclined downwardly and outwardly, as clearly shown in Fig. 1. The sliver to be coiled is delivered to the passage 21 by calender rolls 22, mounted above the coiler head and to which the sliver is delivered from the usual drawing rolls (not shown).
A storage can C is mounted below the coiler head 12 3 but showing a slight and recelves the sliver as it is delivered from the passage 21 of the coiler head. As the sliver is thus delivered, it is coiled in the can C by the rotation of the head 12.
2,770,016 Patented Nov. 13, 1956 The mechanism thus far described is of usual commercial form and in itself forms no part of the present invention, which relates particularly to the special outlet construction shown at the lower end of the passage 21 in the head 12.
Reference to the drawings will show that at the rear side of the raised structure 20, the rear wall 30 of the passage 21 is displaced outwardly to provide the delivery passage 21 with a rearward enlargement 33, which enlargement is rearwardly contracted and is substantially U-shaped in section.
While this change in the construction of the coiler head appears relatively simple, very unusual results are accomplished by the use of this changed construction. As the coiler head 12 rotates clockwise, the drag of the sliver in the can will cause the sliver being delivered by the head 12 to be pressed closely against the rear wall 30 of the passage 21. As the sliver leaves the passage 21, it will thus be drawn into the recess or enlargement 33 and will be radially centered therein, regardless of its size or composition, so that the effective diameter of the delivery path of the sliver will remain substantially constant, regardless of the size or composition of the sliver. If the coiler head is to be reversed, a duplicate passage enlargement 33a may be provided as shown in Fig. 4.
It thus becomes possible to use a single coiling head to produce satisfactory results with slivers of widely varying characteristics. This avoids all necessity for changing the heads and for providing multiple parts.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
1. In a sliver coiler, a rotated coiler head having structure providing a downwardly-inclined and converging sliver-delivery passage of substantially circular cross section, and said passage having its extreme lower end portion only provided with a sliver-locating lateral enlargement in a side wall portion of said passage and of limited angular extent only and at the following side of said passage, having reference to the normal direction of rotation of said coiler head, and said enlargement being substantially U-shaped in sectional plan adjacent the sliver-delivery locus, and being effective to maintain the delivery path of slivers of different diameters at a substantially uniform radial distance from the axis of the coiler head.
2. The combination in a sliver coiler as set forth in claim 1, in which the leading wall of said passage is similarly provided with a displaced U-shaped portion and to a limited angular extent only, to thereby provide an additional sliver-locating outlet enlargement for reverse coiler head operation.
